Anti-skid control system for rear wheels
First Claim
1. An anti-skid control system for controlling a braking force applied to road wheels of an automotive vehicle, comprising:
- wheel brake cylinders operatively connected to right and left road wheels at front and rear sides of said vehicle, respectively, for applying braking force to the wheels;
a hydraulic pressure generator for supplying a hydraulic braking pressure to each of said wheel brake cylinders;
actuating means disposed in each hydraulic circuit communicating said hydraulic pressure generator with each of said wheel brake cylinders for controlling the hydraulic braking pressure in each of said wheel brake cylinders;
wheel speed detecting means for detecting a wheel speed of each of said road wheels, and for providing an output signal corresponding to said wheel speed of each respective road wheel;
braking force control means for controlling said actuating means in response to said output signal of said wheel speed detecting means to control the braking force applied to each of said road wheels, said braking force control means controlling the hydraulic braking pressure in each of said wheel brake cylinders operatively connected to said rear road wheels based on the wheel speed of one of said rear road wheels rotating at a lower speed than the other one of said rear road wheels;
turn determination means for determining whether or not said vehicle is turning; and
decrease restraining means for restraining a decreasing operation of the hydraulic braking pressure by said braking force control means for one of said wheel brake cylinders operatively connected to one of said rear road wheels positioned at an outer side for at least a predetermined time period when it is determined by said turn determination means that said vehicle is turning.

Abstract
The invention is directed to an arrangement for controlling a braking force applied to each of road wheels of a vehicle depending upon a braking condition, with a hydraulic braking pressure supplied to each of the wheel brake cylinders through an actuator. The actuator is controlled by a braking force controller into which output signals of wheel speed sensors are fed. The hydraulic braking pressure applied to each of the wheel brake cylinders is controlled by the braking force controller in accordance with each wheel speed. And, it is determined whether the vehicle is turning or not. If the vehicle is turning, the hydraulic braking pressure in a wheel brake cylinder operatively connected to one of the rear road wheels positioned at the outer side is controlled such that a decreasing operation of the pressure is restrained for at least a predetermined time period.
